VIEGA transition fitting 22 mm x 1/2" bronze (model 101664)

VIEGA transition fitting 22 mm x 1/2" bronze is a metal adapter designed to connect a 22 mm copper or plastic pipe to a 1/2" threaded fitting. Constructed from bronze, the fitting offers corrosion resistance and mechanical strength suitable for potable water and general plumbing systems. The component provides a reliable change of pipe diameter and connection type, enabling the integration of threaded valves, fixtures or other devices into pressurized piping circuits.

Advantages

The bronze construction ensures long-term resistance to corrosion and dezincification in typical plumbing environments. Precision machining of the threaded end and the smooth sealing surface on the pipe side provide a secure mechanical and threaded joint with minimal risk of leaks when installed correctly. The compact form factor allows installation in confined spaces and compatibility with common 22 mm tubing and 1/2" threaded components used in household and commercial plumbing.

Suitable for

• Connecting 22 mm distribution pipework to 1/2" threaded valves and fixtures
• Plumbing repairs where a change from push-fit or soldered pipe to a threaded connection is required
• Potable water installations and general domestic plumbing systems

Key specifications

• Material: bronze for enhanced corrosion resistance
• Pipe connection size: 22 mm
• Threaded connection: 1/2" (female or male as required by system — verify before installation)
• Application: potable water and general plumbing
• Design: compact transition fitting suitable for confined installation spaces

How to use

Prepare the 22 mm pipe by cutting squarely, deburring the internal and external edges, and ensuring the pipe end is clean and free from contaminants. For mechanical or compression-style joints follow the fitting manufacturer's instructions for insertion depth and tightening torque. For threaded connections apply an appropriate pipe thread sealant or PTFE tape to the 1/2" thread and tighten to the recommended torque to achieve a secure, leak-free joint. After installation, pressurize the system and inspect all joints for leaks; re-tighten as needed according to standard plumbing practice.

Usage recommendations

Confirm material compatibility with the fluid media and local plumbing codes prior to installation. Use appropriate installation tools and follow recommended torques to avoid over-tightening, which can damage threads or the fitting body. When connecting to potable water systems, ensure seals and sealants are approved for drinking water contact.
